摘要：

The promoter nature effect on the sensitivity of Mo/Al2O3, Ni-Mo/Al2O3, Co-Mo/Al2O3, and Ni-Co-Mo/Al2O3 catalysts to dodecanoic acid in the hydrotreating of a mixture containing dibenzothiophene and naphthalene has been investigated. The experiments have been carried out using a flow-through setup. The catalysts have been prepared using the PMo12 heteropoly acid, Co(Ni) citrates, and Co2Mo10 heteropoly acid and have been characterized by high-resolution transmission electron microscopy. The highest hydrodesulfurization activity in the presence of dodecanoic acid is shown by the trimetallic catalyst Ni-Co-Mo/Al2O3. The introduction of Ni is favorable for dodecanoic acid conversion via the hydrogenation route, thus increasing the C-11 : C-12 ratio in the conversion products. Effective dodecanoic acid adsorption constants under the hydrotreating conditions have been calculated using the Langmuir-Hinshelwood model.
